VESSEL FOR THE TRANSPORT OF LIQUEFIED GASES.

Application filed May 18, 1922.

To all whom it may concern:

Be it known that I, HEINRICH SCHMATZ, a subject of Czechoslovakia, and residing at Berlin, Konigin Augustastr. 4:3, Germany, have invented certain new and useful Improvements in or Relating to a Vessel for the Transport of Liquefied Gases, of which the following is a specification.

This invention relates to vessels for the transport of liquefied gases in which the gases are contained in vessels comprising two compartments separated by a vacuum chamber.

Vessels for the transport of liquefied gases which have double walls necessitate very long necks. When a vessel of this nature is tilted out of a vertical position the inner container comes into contact with the outer container so that an equalization of temperature takes place between these two The inner container therefore must turn relatively to the outer container, about the upper edge of the neck of the vessel. This causes stresses on the upper edge of the neck, which destroy the tight joint between the containers at the neck The present invention ensures equalization of temperature between the two containers when the vessel is tilted, not by a direct contact between the two containers, but by means of a heat transmission body, such as for instance an aluminium ball mounted in an exhausted chamber situated between the two containers and establishing metallic connection between them.

The invention is clearly illustrated in the accompanying drawings in which Fig. 1 is a part sectional and part elevational view of the conveyor receptacle.

Fig. 2 is a similar view showing the receptacle tilted to 90 degrees, and

Fig. 3 is a similar view showing the receptacle tilted more than 90 degrees.

Referring to the drawings a is outer container and Z) an inner container, both made of metal and connected together at the neck, 0 is the ball of metal such for example as aluminium.

When the vessel is in the upright position as shown in Figure 1, the ball is situated at the bottom of the vacuum chamber and resting on the surface of the outer container, ithout touching the inner container, When the vessel is tilted, the ball rolls on Serial No. 561,934.

the surface of the outer container towards the neck of the vessel. The dimensions of the ball are so calculated that when the ves sel is tilted through 90, the ball will not come into contact with the surface of the inner container (Figure 2). If indeed the inner container were to bear with all its weight upon the ball in this position the wall of the inner container (which must be very thin), would be dented or otherwise 1n ured; moreover, the heat must be transmitted only when the vessel is turned through more than 90 (Figure 3) in order to force the attendant to tilt the vessel to the required extent.

Owing to the arrangement of the ball, the neck of the vessel can be made shorter and given approximately the shape shown in the drawing.

The connection between the two containers at the upper edge of the neck is exposed to smaller stresses and can be prac tically considered as rigid.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. A vessel for receiving liquefied gases including a casing, a double walled vessel body in the casing provided with a vacuum chamber between the double walls, and an element arranged in the vacuum chamber and forming a heat conducting connection between the inner and outer walls of the vessel body when the vessel is tilted through an angle greater than 90.

2. A vessel for receiving and transporting liquefied gases including an outer sup porting casing, a double walled vessel body mounted on the casing and having a vacuum chamber between the walls and a movable ball in the vacuum chamber between the inner and outer walls and having a diameter for establishing a heat conducting connection between the inner and outer walls only upon the vessel being tilted through an angle greater than 90". i

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
